Interfacing The PCF8583 Real Time Clock With PIC Microcontroller – MikroC

image-323
The PCF8583 is a small 8-pin clock and calendar chip from NXP Semiconductors with full binary coded decimal (BCD) clock/calendar plus 2048 RAM (256 by 8 RAM memory) that is used in microcontroller based systems to provide real time date and time information. Data and Addresses are transferred serially through a bidirectional I2C bus. The PCF8583 RTC provides year, month, date, hour, minute and second information. The built-in word address register is incremented automatically after each written or read data byte. Address pin A0 is used for programming the hardware address, allowing the connection of two devices to the bus without additional hardware

Digital Clock using PIC Microcontroller and the DS1307 Real Time Clock – MikroC

image-128
Real Time Clock and Calendar functions are very important in many projects especially in data logging devices where a real time stamp is required in each record. This clock uses the DS1307 which is a low power serial real time clock/calender with full binary coded decimal (BCD) clock/calendar plus 56 bytes of Non Volatile Static RAM. This chip provides year, month, date, hour, minute and second information. The end date of months is automatically adjusted for months fewer than 31 days including leap year compensation up to year 2100. In this article we are going to design a digital clock using the DS1307 RTC with MikroC Pro for PIC compiler
